In 2024, the World Health Organization (WHO) has proposed revised hemoglobin cutoffs for diagnosing anemia in children aged 6-23 months, pregnant women in the second trimester and those residing in elevated areas with the aim of increasing the sensitivity and ensuring uniformity in diagnosis. There are no major changes in other domains.

Very preterm infants often need red blood cell transfusions (RBCT) during intensive care and are at risk of iron overload. This study reviewed the records of 65 very preterm neonates who required at least one RBCT to ascertain the iron status using serum ferritin levels at 4-6 weeks age before oral iron was commenced. High serum ferritin level was found in 52.3% (n = 34) neonates. Need for > 1RBCT was significantly and independently associated with iron excess (P < 0.001). Increased ferritin noted following transfusions in neonatal period can have implications for determining the appropriate time for starting iron supplementation in this subgroup of neonates.

Objective: To compare the diagnostic efficacy of multiplex polymerase chain reaction (PCR), Mycobacterium leprae-specific repetitive element (RLEP) PCR and loop-mediated isothermal amplification (LAMP) PCR in the diagnosis of pediatric leprosy as an alternative to slit-skin smear (SSS) examination.

Methods: A cross-sectional study was performed on 26 children aged 0-18 years with characteristic skin lesions of leprosy. SSS examination for acid fast bacilli (AFB) was performed for all children. Additionally, urine, stool and blood samples were tested by three PCR techniques - multiplex, RLEP and LAMP. The results of these tests were compared with each other and with results of SSS examination for acid fast bacilli (AFB) using appropriate statistical tests.

Results: Out of 26 patients studied, SSS examination was positive for AFB in 7 cases (26.9%). In blood samples, the positivity of multiplex PCR, RLEP PCR and LAMP PCR was 84.6%, 80.8%, and 80.8%, respectively. Multiplex PCR in blood samples was positive in 100% (n = 7) of SSS positive cases and 84.2% (16 out of 19) of the SSS negative cases (P < 0.001). The positivity of all PCR methods in urine and stool samples was significantly lesser than in blood.

Conclusion: Multiplex PCR in blood sample is a superior diagnostic tool for pediatric leprosy compared to RLEP PCR and LAMP PCR as well as SSS examination.

Objectives: To compare the urinary bisphenol A (BPA) levels in bottle-fed and never bottle-fed infants and under-five children and to determine the impact of bottle-feeding practices and sociodemographic factors on urinary BPA levels.

Methods: A community-based cross-sectional study was carried out on children aged between 2 to 60 months attending the Anganwadi centres in Chandigarh.

Results: Urine samples were collected from 184 children, out of which 94.56% (n = 174) children had detectable urinary BPA levels. The mean (SD) BPA level was 2.74 (2.60) ng/ml and BPA was detected in 93.9% of 'ever' bottle-fed children (n = 93/99) and 95.3% of 'never' bottle-fed children (n = 81/85) (P = 0.69). On multivariate regression analysis, there were no significant predictors for high (≥ 75th percentile) urinary BPA levels. Still, the odds of urinary BPA levels ≥75th percentile showed higher trend for significance among children from middle/higher socioeconomic background in reference to lower socioeconomic stratum (adjusted OR 7.02; 95% CI 1.24, 133.25; P = 0.07) and among children whose feeding bottles were brushed once or twice daily in reference to group with no daily brushing (adjusted OR 3.92, 95% CI 0.95, 20.56; P = 0.07).

Conclusions: Although feeding with plastic bottle did not emerge as a statistically significant risk factor for BPA exposure, yet detection of BPA levels among majority of study children signals urgent need for unmasking exposure to other sources given the potential long-term toxicity of BPA among infants and young children.

The desire for parenthood among infertile individuals is often fulfilled by resorting to the ever-evolving Assisted Reproductive Techniques (ART). Since the birth of Durga, India's first baby born using ART in 1981, the lucrative fertility industry has grown exponentially in our country. The Government of India passed the Assisted Reproductive Technology (Regulatory) Act in 2021 to provide regulatory support to these services. The legislation offers clarity on various aspects of ART, including measures to safeguard children born through these procedures. The effective implementation of the ART Act is crucial to ensure that ART services become affordable, ethical, and socially acceptable in India. This article aims to discuss the controversies with ART services and issues that could compromise the wellbeing of children, while highlighting the provisions provided under the Act to address these.

Objective: To assess weight velocity and the age at peak weight velocity and to construct weight velocity percentiles in 4-17-year-old apparently healthy Indian children.

Method: This longitudinal study enrolled 1045 children (588 boys) from Pune belonging to middle and upper socioeconomic class aged 4-17 years. The study parameters included annual height and weight measurements recorded longitudinally from 2007 to 2013. A total of 5225 weight velocity measurements (2940 on boys) were computed. Age- and gender-specific smoothened weight velocity percentiles (3rd, 10th, 25th, 50th, 75th, 90th and 97th) were constructed using LMS chart maker.

Results: The median weight velocity was low in boys and girls at 4 years, thereafter it increased to a peak of 4.6 kg/year at 13 years in boys, then declined to 1.1 kg/year at 17.5 years. In girls, median weight velocity peaked to 4.0 kg/year at 11 years, then declined to 0.8 kg/year at 17.5 years. Peak velocity-centred analysis revealed higher peak velocities of 7.5 kg/year at 13.1 years and 6.6 kg/year at 12 years in boys and girls respectively.

Conclusion: Weight velocity percentiles are presented for 4-17-year-old apparently healthy Indian children.

Objective: This study aimed to assess the efficacy of different oral iron preparations prescribed for prevention of iron deficiency anemia in healthy infants.

Methods: This retrospective study enrolled infants aged between 6 and 12 months who were initiated on iron prophylaxis at four months of age. Enrolled children consistently used specific iron preparations (ferrous, ferric or liposomal iron) and had their complete blood counts and serum ferritin levels assessed within the 6-12 month timeframe. Blood values and iron prophylaxis type (ferrous (Fe+2), ferric (Fe+3), liposomal iron) were recorded. Chi-square test was used to compare the hemoglobin and ferritin levels levels between groups. Univariate and multivariate regression analyses assessed the risk of anemia.

Results: The study included 371 children (ferrous sulphate - 60, iron hydroxide-polymaltose complex - 137 and liposomal ferric pyrophosphate - 174) with a mean (SD) age 9.1 (1.3) mo. Iron deficiency in different groups were: liposomal iron (46.0%), ferric iron (44.5%), and ferrous iron (5.0%). Mean (SD) serum ferritin levels (µg/L) were higher in the ferrous group [30.1 (10.8)] compared to infants receiving ferric [17.6 (14.50)] and liposomal iron [15.4 (12.1)] (P < 0.001). Mean (SD) hemoglobin levels (g/dL) were significantly higher in the ferrous group [12.4 (0.8)] compared to ferric [11.9 (1.1)] and liposomal iron group [12.0 (1.1)]; P =0.008. Multiple regression analysis showed that ferrous group was associated with a lower risk of iron deficiency [OR (95% CI) 0.04 (0.01-0.15), P < 0.001].

Conclusion: Ferrous iron demonstrated superior efficacy compared to ferric and liposomal iron. Further studies are needed to establish alternative iron preprations in children.

Objective: To assess the impact of COVID-19 on immunization coverage and delayed vaccination among tribal children in the Khordha district of Odisha state.

Methods: A cross-sectional rapid epidemiological survey was conducted using a standard WHO (30 × 7) cluster survey with 30 tribal villages under the Community Health Centre (CHC), Mendhasala, Odisha, as clusters and seven children from each cluster. A total of 14 children from each cluster; seven each born in 2019 (2019 cohort) and 2020 (2020 cohort), amounting to 420 children were included. The dates of vaccination and related details were obtained from the mother and child protection cards alongside a pretested, semi-structured questionnaires administered to the mothers or primary caregivers. Immunization coverage and delayed vaccination rates were compared between the two cohorts.

Results: Full immunization coverage was 81.9% and 77.6% in the 2019 and 2020 cohorts, respectively. A significant decline in full immunization coverage was seen for 14 weeks (Pentavalent-3) vaccine in 2020 cohort (P = 0.01). The proportion of delayed vaccination for scheduled vaccines at birth, 6 weeks, 10 weeks, 14 weeks, and 9-12 months for 2019 cohort and 2020 cohort were 8.6%, 6.7%, 18.1%, 19.5%, 22.4%, and 21.9%, 26.7%, 30.5%, 19%, 16.2%, respectively. However, delayed vaccination rates among the 2019 and 2020 cohorts were not statistically significant.

Conclusion: Our study findings showed a little decline in immunization coverage in tribal areas during the pandemic.
